The free end ofthe tube 37 is connected into the mouth piece of a. windvinstrumentthrough which the tune is produced. The air current passing from thetone chamber in through the horn 32 will vibrate the reed 34 originatinga tone and the volume and quality of this tonewvill depend largely onthe force of the air pressure as modified by the particular instrument.through which it is delivered. The pitch of the tone will depend on thelength of the reed and column of air vibrated thereby and differenttones requiredv to produce the music described are obtained by a properselection of the tone chambers in which the tone is originally producedand the proper manipulation of the valves of the corresponding windinstrument. It is to be here noted that the corresponding valves 253 and42 are manipulated in unison through a series of electrical contacts sothat the branch pressure line 17 may be connected through any selectedtone chamber int-o the tubing 37 and the tones of the instrumentconnected therewith thus varied.

Each instrument is held in position by a suitable bracket 52, and hasthe usual valves 53, the number of valves varying in accordance with therangeand design of the instrument. The valves are of the usualconstruction and for the usual purpose, being provided to vary the tone1produced. The valves ,53 may be depressed by means of the controllingrfingers 54 which are pivoted at one end to the casing and whose otherends are aligned over the valves 53. These fingers carry metallic platesas 55 which are alignedl over suitable electromagnets 56 each ofwhichare wired separately in the electrical circuits 57, and when theelectro-magnets 56 are energized the corresponding fingers will bedepressed thus operating the valves Various tones may be obtained byoperating the valves 53 in suitable combinations with any one of thetone chambers 1S and these various cornbinations of the valves 53 witheach of the various tone chambers 18 in turn will produce a suliicientrange of tones for executing music, and of course this range may beenlarged .in scope by providing additional tone chambers 18 andconnecting them with the tube 37 in the manner hereinbefore describedand as illustrated in Figure 4.

In Figures 18 to 20, inclusive, I have Shown the key boards arranged inright and lett hand banks similar tothe key board of the ordinary pipeorgan. The numerals 58 and 59, respectively designate the left and righthand key boards proper Whereon are mounted the keys 60 and 61 which aresupported on yieldable seats as 62 and 63. These keys embody electricalswitches formed with the fixed and the opposing movable contactpoints64, 65 and 66, 67, re

spec-tively, the fixed contact points being connected to the commonreturn 68 which is connected through the battery or other source ofpower 38, to a common return or ground, and movable contact point-sbeing connected with the electrical wiring 69 and 70, respectively. Thecorresponding' electromaguets Q8, 50, and are connected into therespective circuits through the electrical wiring 29, 5l and 57 so thatby manipulating the keys 60 circuits may be establishedv to operate 'thevalves 2Q, 4Q and 53 at the will of the operator.

The full understanding of the manner in which tones can be produced ofthe proper pitch to make a musical scalo can best be shown byexplainingin detail the production of party of a scale. The valves whichare embodied in the construction of the brass instruments of a. brassband are commonly designated as the first valve, referring to the valveclosest to the mouthpiece of the instrument and farthest from the bellof the instrument which is usually manipulated by the first or indexfinger of the musician when playing the instrument.; the second valvereferring to the middle valve of, the instrument, which is usuallymanipulated by the second or middle. finger of the musician when playingthe instrument; and the third valve referring to the valve farthest fromthe mouthpiece of the instrument, and closest to the bellk of theinstrument. Any tone produced in playing the instrument withoutmanipulating the valves embodied in said instrument is known as an opentone. The valves of said" instrument are so connected with the tubingcomposing said instrument that when the second valve of said instrumentis depressed it adds a certain amount of tubing through which the airmust pass in going through the instrument and thereby lengthening thecolumn of air which is caused to vibrate within the instrument, therebyproducing the tone. The first valve of the instrument when depressedaccomplishes the same result as the second valve, with the exceptionthat the first valve when depressed adds twice the amount of tubing thatthe second valve adds; and the third valve, when depressed, adds anamount of tubing equal to the amount added by the first and secondvalves combined. Each instrument will produce several open tones ofdifferent pitches, the difference in pitch of the different tones beingcaused by the different frequency at which the column of air within theinstrument is made to vibrate. The different pitches of the various opentones of any brass instrument of the brass band are always tones of apitch which are known as harmonics of the fundamental tone or pitch ofthe instrument. The fundamental, tone or pitch of the instrument 'lll isthe open tone oft the lowest pitch which the instrument Will produce. lnan instru nient so built or construc'ec1 that its fundamental tone isthe musical pitch 53, the i tones, in an ascendi scale, 'will i Cilf C)7 (-LC (if Cy i re known respectively, all ot which ias hr3-1- ioniesthe leerer pitched o'T lunda- `4 lif e" or' the insti nnent.

By the use of the Various other tone chambers, with and Without thedepression ot the Valves or the instrument connected with the tubing 37,tones of the various pitches necessary to complete a` musical scale andthe entire compass ot' the instrument may be produ ed. The 'valves otthe instrument may be depressed separately or in Various combinations1with each other as is necessarilv to produce tones ol the pitchrequired.

To explain the manner in which the valves 22 and ft2 are operated eitherindependently ot the valr 53 et the instrument or with these said-Valves et the instrument the electrical Wiring or connections necessarywith the l` lvs Gl, in the keyboard 59, will be exed in detail for theproduction of tones fied from Gr to in a descending '.le b e samepitched tones herein- .ore )ed together with the action necessa cirproduction.

rihe electrical Wire 70 running from the D key is connected with theWire 69, shown in Figure 4, controlling through the electroinagnets 28and 50, the operation of that tone chamber 18 as has previously beendesignated as tone chamber E,-and is also connected with Wire, orcircuit 57, controlling` through the electro-magnet 56 the operation ofthe first valve of the instrument, which is connected with the tubing37. lV ith these connections made, when the D key is depressed thecontact pointsr 66 and 67 will be brought vtogether and thek electricalcircuit completed causing the electro-magnets 28 and 50 to becomeenergized thereby `opening the Valves 22 and 42, and allowing the airWhich is being held under pressure in pressure tank 12, shown in Figure2, to pass through tone chamber E and through tubing 37, and through theinstrument attached to said tubing` 37, and the depression of the D key,bringing together contact points 66 and 67, also causes theelectro-magnet 56 controlling` the operation. of the first lvalve of theinstrunent attached to said tubing 37, to become energized thereby,causing the depression of the first va ve, oi said instrument, therebylengthening the column of air Within the instrument, and therebyproducing the musical tone of the pitch 'D as desired.

In like manner by the use of additional tone chambers 18, and the use ofthe valves embodied in the brass band instruments tones of other pitchesare produced and sufficient Varied pitches are produced to include thecomplete range of pitch or compass of the said band instrument. Thelength of the column of air which is caused to vibrate is varied by theuse of the valves embodied in the band instrument through which itnasses '.ihe dil'lierent frequencies at which tris said column otl airvibrates is varied by the use ot' the dille-rent tone chambers 18.

lt may often be tou-.nd desirable, where certain parts are to be playedin unison, to provide a coupling device tor coupling the instrumentstogether so that said parts an be played from the same keys. This isillusw trate/d in Figures E and 21 wherein the numeral 71 designates along bracket anchored to the framework behind the richt, hand key boardand this bracket has transverse bar 72 or insulating material iiiledthereon, and adjacent this bar lies ar row ot contact points 7 3 otmetal, forming av good conductor and each insulated -trom the otherI andconnected to which are the binding` posts 7% to which the wiring 70 isalso connected. A long bar 75 is located above the key board andprovided with hand knobs as 76. irttached at their outer ends to the bar7 5 and extending through the bearings in thecasing are the couplingbars 77 whose inner ends have the binding posts 7S which are connectedwith the wiiing7$}. The wiring is connected into the circuit ot thesolenoids controlling the instruments to be coupled in. lVhen it isdesired to `couple instruments together the coupling bars may be pulledoutwardly, in the position shown in Figure 21, in which case the bindingposts 78 will be brought into contact with the conductors 73, thusforming the coupling. lVhen torced inwardly into the position shown inFigure 20 the binding post 7 S will be carried into contact with theinsulator 7 2 breaking the circuit.

In controlling two of the band instruments Ifrom the same key board thecoupling device is used. rEhe knob 76 is pulled out or forward, bringingwith it the bar and the coupling bars 77, and the electrical connectionor binding posts 78, bring each ot their binding posts into connectionwith the contact point 73 which in turn is connected with the wire 70,ruiming from the key 01 directly in trent of said contact point 73.|These various binding posts are each so connected with wires ot'electrical circuits that they control the flow ot electrical currentthrough the proper electro-magnets to produce on another bandinstrument, other than the one with which the keys ot the keyboard isregularly connected, a tone ot the same pitch or a tone pitched oneoctave, or it desired, a fractional part thereof, lower or higher in themusical scale than the. tone which is produced by the instrument withwhich said key is so electrically connected in circuit as to permanentlycontrol the production ot.

The basses and altos are also controlled through the foot pedals 80which are pivotally mounted and provided with the movahle Contact pointsS1, 81 which oppose the lined contact points 82, 82, said contact pointsbeing connected with the electromagnets of the controlling valves QS, 50and which control the. bass and alto instruments through a key regulatorshown in detail in Figures Qi, 24 and Q5. This regulator includes bankot key bars indicated by the numerals 83 to 9st, inclusive,respectively, having the hand knobs numbered to 106 inclusive,respectively, caen labeled to indicate the corresponding key. lllithinthe casing tiere are arranged the vertical insulating bars 107 andadjacent them the vertical conducting bars 108, with the latter of Hwhich wired to the point 8l. The regulator bars S3 to 94 respectively,each have the binding post anchors 109 to 120 inclusive, respectivelycarried thereby which work through suitable bearings in the casing andtheir inner ends carry binding posts which carry the flexible tonguesdesignated respectively by the numerals 132 to 15:3 inclusive. rlhesetongues are preferably Li-shaped in form to embrace said bars 107 to10S, and connected to these respective binding posts there is electricwiring forming a part et the circuit into which the electro-magnetscontrolling the bass and alto instruments are connected. The key desiredmay be selected and the corresponding key bar 'forced inwardly tocomplete an electrical circuit through the bars 108 and the manipulationof the foot pedals will then operate to produce the chords on the basschords instruments in the key selected.

The manner in which this chord operating device operates the electricalcircuits necessary to control and operate the C chord will be described.rlhe common C chord, as do the chords in all other musical keys,consists ot what are commonly called three changes. These changes aregiven bc.- low, the letters indicating the musical pitch ot the tone.

Second change: l"-rl-C.

Third change: G-B-D.

These changes as shown above are listed on an ascending scale, that is,the C is the lowest pitched tone in the iii-st change, whereas the C inthe second change is the highest pitched tone in that change, and ispitched one octave higher than the C in the first change. In ordinaryband music it is customary to have the bass horn produce the lowestpitched tone, and to produce the two higher pitched tones produced onthe alto horns.

The toot pedals S0 will be considered iirst foot pedal, second tootpedal and third foot pedal, numbered from right to left, and willcontrol the first. second and third changes of the musical chords. Thethree llO vertical conducting bars 108 on the letty will be knowny asthe bass conducting bars, and the three vertical conducting bars 108 onthe right will be known as the alto conducting bars. The bass conductingbars 108 will be known as first bass bar, second bass bar, and thirdbass bar, designated from right to left; and the flexible U-shapedtongues 132, used to embrace and engage said bars will be known as firstbass engaging tongue, second bass engaging tongue, and third baseengaging tongue, being opposed to the first bass bar, second bass bar,and third bass bar, respectively. The three.

vertical conducting bars on the right known as the alto conducting bars,will be known as the first also bar, second alto bar, and third altobar, respectively, from left to right; and the liexible `Ushaped tongues132, used to embrace and engage saidbars will be known as first altoengaging tongue, second alto engaging tongue and third alto `engagingtongue, being opposed to the first alto bar, second alto bar, and third'alto bar, respectively. That portion of the pedal that lies under theheel of the individual operating the apparatus will be designated as theheel end of the pedal, and that portion of the pedal 80 that lies underthe toe of the individual operating the apparatus will be designated asthe toe end of the pedal. The contact points 81 and 82 are so wired orconnected into circuits that when the heel end of the first foot pedalis depressed the irsty bass bar will be thrown into circuit, when theheel end of the second foot pedal is depressed the second bass bar willbe thrown into circuit, and when the heel end of the third foot pedal isdepressed the third bass bar will be thrown into circuit, and when thetoe end of the lirst foot pedal is depressed the first alto bar will bethrown into circuit, when the toe end of the second foot pedal isdepressed the second alto bar will be thrown into circuit, and when thetoe end of the third foot pedal is depressed the third alto bar will bethrown into circuit. The circuits of which these various bass and altobars become a part upon the depression of the foot pedals will beIcoinpleted through the flexible U-shaped tongues and their respectivebinding posts and from these said binding posts through various wiresconnected with the proper electromagnets 28 and 50, belonging to andkconnected with the proper units 2 to produce the tones of the pitchdesired upon the in-k struments desired, and when necessary to producethe tones of the pitch desired the wires connected with these saidbinding posts will be connected also with electro-magnets 56 associatedwith the same, said 'instru ments thereby operating, as is necessary,the valves contained and carried by these said instruments. The mannerin which the U-shaped tongues 132 are connected into electrical wiringis as follows:

The first bass engaging tongue 132 is connected through the binding footto which it is attached with electrical wiring running to and connectedwith the proper electro-magnets, the` energizing of which will cause atone of the musical pitch C to be produced through and by a bass brassband instrument, attached to tubing 37 leading from one of the units 2.

The second bass engaging tongue 132 is connected through the bindingpost to which itis attached with electrical wiring running to andconnected with the proper elec- -i tro-magnets, the energizing of' whichwill cause a tone of the musical pitch F to be produced through and by abrass band instrument attached to tubing 37 leading from one of theunits 2.

1rd 211i@ engagn h the bind conneoed throng The th' kaa Connected withthe pressure tank 122, through the line 13 and its purpose is tomaintain a predetermined pressure by controlling the motor whichoperates the aii compressor.k This gauge embodies the conventionalcasingv 163 enclosing any Well known type kof pressure gauge mechanismwith which the hand 154 is connected.y Surrounding the casing there is astationary rmg 165 whose outer side is formed with a gauge dial and onthe inside of the casing 1 there is a rotatable ring 166 formed withspur gear teeth which are in mesh with the spur gear wheel 167 which isfixed to the stern 168. This stem works in a bearing in the margin ofthe rin 165 and carries the hand knob 169 by which it. may be rotated.The ring 166 carries an arcuately arranged krow of contact points 167with which the freel end of the hand 164 contacts ysuccessively as itmoves around the dial and said hand thereby Cuts resistance coils intothe circuit with which the motor is connected. As the pressure increasesthe hand 164 moves around the dial and cuts in additional resistancecoils 171 thus operating to retard the, motor and decrease the pressure.This gauge thereby serves as a pressure regulator. The dial may beadjusted, by turning the (rear wheel 167 through the hand knob 169 andthe contact points 170 being connected to said dial will becorrespondingly adjusted with it so that in maintaining thepredetermined pressure the dial may be adjustedto the proper position soas to cut into the circuit resistance in order to maintain the desiredpressure.
